Journalist Liza is said to be “irate” that Liam’s lawyers are “insulting” her with such an order after she kept quiet during her pregnancy and birth.

According to the New York Post DNA tests have confirmed the 40-year-old is the father of Liza’s child but Liam – who is still wed to third wife Nicole Appleton , 38, has yet to make any public comment.

A friend of the celebrity journalist, who began a relationship with Liam after she interviewed him for the New York Times in 2010 , said: “Liza had no problem signing a confidentiality agreement regarding Liam’s finances, but Liam’s lawyers discreetly tried to add on an agreement that Liza never disclose any personal details of their relationship.

“She’s fed up. Liza and Liam were so close, they were picking out baby names together. She won’t sign.”

Gallagher last spoke to his wife on July 17, to admit his betrayal as she holidayed in Florida with Gene and Lennon, 13 – his first son with first wife Patsy Kensit, 45.

He has a fourth child Molly, 15, with singer Lisa Moorish, 40.

Gallagher is said to be dating Debbie Gwyther, who he was seen drinking with in Ibiza as reports he made a US journalist pregnant broke.

Debbie, 31, was his personal assistant but left his band Beady Eye’s management company over claims they were “too close”.

Now it seems they are dating after his split from wife Nicole Appleton.

Wife Nicole, is being supported by her sisters and wrote on Twitter this week: “NEVER let people, life & unpleasant circumstances change the HAPPY vibrant person you USED TO BE.”
